Of the others only Gandalf might be expected to master him – being an emissary of the Powers and a creature of the same order, an immortal spirit taking a visible physical form. In the 'Mirror of Galadriel', 1381, it appears that Galadriel conceived of herself as capable of wielding the Ring and supplanting the Dark Lord. If so, so also were the other guardians of the Three, especially Elrond.
But this is another matter. It was part of the essential deceit of the Ring to fill minds with imaginations of supreme power.
... If Gandalf proved the victor [using the One against Sauron], the result would have been for Sauron the same as the destruction of the Ring; for him it would have been destroyed, taken from him for ever. But the Ring and all its works would have endured. It would have been the master in the end.

Letter 246
'...True-hearted Men, they will not be corrupted. We of Minas Tirith have been staunch through long years of trial. We do not desire the power of wizard-lords, only strength to defend ourselves, strength in a just cause. And behold! in our need chance brings to light the -Ring of Power. It is a gift, I say; a gift to the foes of Mordor. It is mad not to use it, to use the power of the Enemy against him. The fearless, the ruthless, these alone will achieve victory. What could not a warrior do in this hour, a great leader? What could not Aragorn do? Or if he refuses, why not Boromir? The Ring would give me power of Command. How I would drive the hosts of Mordor, and all men would flock to my banner!'
Boromir strode up and down, speaking ever more loudly: Almost he seemed to have forgotten Frodo, while his talk dwelt on walls and weapons, and the mustering of men; and he drew plans for great alliances and glorious victories to be; and he cast down Mordor, and became himself a mighty king, benevolent and wise.

‘Comfort yourself!’ said Gandalf. ‘In no case would Boromir have brought it to you. He is dead, and died well; may he sleep in peace! Yet you deceive yourself. He would have stretched out his hand to this thing, and taking it he would have fallen. He would have kept it for his own, and when he returned you would not have known your son.’
...
[Denethor:] ' Nay, it should have been kept, hidden, hidden dark and deep. Not used, I say, unless at the uttermost end of need, but set beyond his grasp, save by a victory so final that what then befell would not trouble us, being dead.’
... ‘Nonetheless I do not trust you,’ said Gandalf. ‘Had I done so, I could have sent this thing hither to your keeping and spared myself and others much anguish. And now hearing you speak I trust you less, no more than Boromir. Nay, stay your wrath! I do not trust myself in this, and I refused this thing, even as a freely given gift. You are strong and can still in some matters govern yourself, Denethor; yet if you had received this thing, it would have overthrown you. Were it buried beneath the roots of Mindolluin, still it would burn your mind away, as the darkness grows, and the yet worse things follow that soon shall come upon us.’
